Tag DISCTOTAL

[SpanishBee]

Good morning, best wishes from Spain.
I have using MusicBee for many years, I have a complete information for my collection, but I have a question:
Why I can not use the tag DISCTOTAL?
I can not search by the this tag.
I have created some virtual tags and custom tags, but I would like to display this tag in the screen, for example:
Album artist
Album
(Virtual tag) = Disctotal - Number of tracks.

Now I can display: number of tracks - duration using a virtual tag, but I can not display the number total of discs because I can not use this tag that exists in the disc information.

English is not my native language so I wait my english will be not too bad.

Thanks in advance.

The tag to use is:
<Disc Count>
